description	The invention relates to a sensor arrangement (9) for a device (1) for additive manufacturing of a component (2) in a manufacturing process in which build material (13), preferably comprising a metal powder, is solidified in a building area (8) in a process space (3) by means of irradiation of the build material (13) with at least one energy beam (AL), said sensor arrangement (9) comprising: - a sensor module (90) designed to detect oxygen molecules in a gas sample (P) that penetrates into the sensor module (90) and to generate an electrical sensor signal (S) based on the amount of oxygen molecules, - a selective filter element (F) designed to filter the gas sample (P) such that at least hydrogen molecules and/or hydrogen ions and/or water molecules and/or hydroxide ions are filtered out of the gas sample (P). The invention further relates to a manufacturing device and to a test method comprising such a sensor arrangement.
